I agree with the tilt...I use a 5 degree angle...When I was researching, I found every opinion between a level table and as much as 30 degrees of tilt...Obviously, the level table doesn't provide any advantage...In my opinion, 30 degrees seems extreme...As stated, at some point, gravity can start to work against you; not just having your workpiece start to slide if not held onto, but at some point you begin "pushing" uphill...As a lot of sources recommend, don't push into the blade; instead, just guide it with the minimum amount of pressure required to keep the workpiece moving through the cut.
